To all whom it may concern.-

Be it known that I, CRowELL M. Drssos- WAY, a citizen of theUnitedStates, residing in the borough of Manhattan, city, county, and State ofNew York, have invented certain new and useful Improvements in Means forDriving Traction-Vehicles, of which the following is a specification.

This invention relates to a traction device for motor-vehicles adaptedfor running on track-rails, and has for its object to provide a greaterextent of driving frictional contact with the crown or upper surface ofthe rail than is provided by'a wheel rolling on the rail and inperipheral contact therewith.

The invention consists, essentially and broadly, in a motor-vehicleprovided with flanged wheels to keep it on the track and with a tractiondriving-wheel which is adapted to bear sidewise or flatwise on some partof the crown of the rail, the plane of the face which bears on the railbeing perpendicular to the axis about which thewheel rotates.

The invention also includes means for transmitting some portion of theload or weight of the vehicle to said driving-wheel in order to effectthe proper frictional contact for driving.

The invention is applicable to all vehicles which run on tracks and havemotors for propelling them through the medium of drivingwheels-such, forexample, as locomotives, trolley-cars, and the like.

In the accompanying drawings, which illustrate several embodiments ofthe invention, Figure l is a side elevation of a part of a vehicleprovided with my invention. Fig. 2 is a vertical transverse section ofthe same, the plane of the section being indicated by line m in Fig. 1;and Fig. 3 is a sectional plan. In these views the intermediary throughwhich the driving-wheel is rotated also transmits a part of the load tothe driver. Fig. 4. is a transverse section illustrating an embodimentwhere the driver is disposed exterior to the track-rail at one side ofthe track.

Fig. 5 is a transverse section showing the driver inclined to thehorizontal. Fig. 6 is a transverse section illustrating an embodimountedin any way ment where the load is transmitted more di-' rectly to thedriver.

Referring primarily to the first three figures of the drawings, 1designates in general the frame and body of a motor-vehicle, and 2, Fig.1, flanged wheels thereof, which run on track-rails T of any kind. 3 isadrivingwheel the side of which is applied laterally to the crown of therail T. The axle or shaft 4 of the driving-wheel is perpendicular to theplane of the face or side of the wheel 3, which bears on the crown ortop surface of the rail. There is a wheel 3 to bear on each track-rail,as seen in Figs. 2 and 3; but asthey are alike a minute description ofone driver and its appurtenances will suffice. As shown in thesefigures, and particularly in Fig. 2, there are two bearing-wheels 5 onan axle 6, which rotates in suitable bearings on the vehicle frame orbody much in the same way as the axle of the driving-Wheels of alocomotive, or, indeed, desired. These wheels will be driven from thepower or motor on the vehicle, and they bear on the respective fiatdriving-wheels 3 and transmit to the-latter a part of the load or weightof the vehicle. In these figures as provided withshort strong teeth 7,which gear with similar teeth 8 on the bearing-wheel 5. The purpose ofthese teeth, which are similar to those of bevel-gears, is to compel thebearing-wheel to rotate the driver positively. 7

It will be noted by reference to Fig. 3 that the face of the driver 3has an extended surface bearing on the track-rail from 2 to 2 much inexcess of that which is obtained by an ordinary driving-wheel bearingperipherthe driver 3 is represented ally on a rail, as in the case of alocomotivedriver, for example, and hence the traction due to the extentof frictional surface in contact and the weight or load will be muchgreater with the construction described than with the ordinaryconstruction.

The drivers (shown inFigs. 2 and 3) are the horizontal plane of thetrack, as shown in Fig. 5. If the driver is placed exterior to thetrack-rail, as shown in Fig. 4, the bearingwheel 5 may have a flange 5"to engage the rail.

The bearing-Wheel as a means of transmitting the load to and impartingrotation to the driver 3 is not an essential. In Fig. 6 acon structionis shown wherein the shaft of the driver 3 is extended upward and bearson its upper end a wheel 9, on the face of which the body of the vehicleis supported through the medium of balls 10. The wheels 3 and 9 are bothfixed on the shaft and. they are driven through any suitable means. Forexample, on a driving-shaft 11 is a bevel-wheel 12, the teeth on whichgear with teeth on the wheel 9.

Obviously the invention may be embodied in various constructions and itis not restricted to any special construction so long as thedriving-wheel bears flatwise or sidewise on the rail either in the planeof the track or slightly inclined therewith.

Having thus described my invention, I claim- 1. A motor-vehicle having adriving-wheel with a lateral face, perpendicular to its axis ofrotation, adapted to be applied to the crown of the track-rail andintermediate means for transmitting a part of the load to saiddriving-wheel and rotating the same.

2. A motor-vehicle having a driving-wheel with a lateral face,perpendicular to its axis of rotation, adapted to be applied to thecrown of the track-rail, and a bearing-wheel for transmitting a portionof the load to the driving-wheel and for rotating the latter.

3. A motor-vehicle having a driving-wheel with a lateral face,perpendicular to its axis of rotation, adapted to bear on the crown ofthe track-rail, said wheel having gear-teeth, and an intermediatebearing-wheel which rests peripherally on the driving-wheel and isadapted to transmit a part of the load to the latter, said bearing-wheelhaving teeth 4 which gear with the teeth on the driver.

at. A motor-vehicle having two drivingwheels with lateral facesperpendicular to the respective axes of the wheels and inclined lessthan forty-five degrees with the plane of the track, said faces beingadapted to bearon the crowns of the respective rails of a track, andintermediate means for rotating said inclined drivingwheels and fortransmitting load thereto.

In witness whereof I have hereunto signed my name, this 29th day ofAugust, 1902, in the presence of two subscribing witnesses.
